So, I think its safe to say that you could go significantly longer than one year on low mileage oil changes. Caterpillar says 15,000 miles is the factory recommended distance between oil changes on my C-10 diesel engine. Thus I change its oil every two years or 10,000 miles which ever comes first. To change 34 quarts of oil annually just because 12 months have gone by, irrespecutful of miles accumulated, is wasteful and frankly, irresponsible.
Well frankly, one of the rudest non value post I've read in along time. Have an opinion? Great. Do you know how everyone else uses their coach, or the environment they use them in? Of course not. But yet still up on your high horse with such a comment as
'is wasteful and frankly, irresponsible.'
This board is a group of members sharing info, helping each other learn, and from time to time some good old fun.
If you spent just 30 minutes searching the subject of 'oil change frequency' (Or similar.) - you would see that not many different usages of our equipment exists.
Me? I follow what both Cummins and Allison says to do, as well as Country Coach in regards to my chassis servicing. So that is yearly, as I've never had severe enough duty, or miles, to do otherwise. (Came close at just about 13.8K miles round trip on our 2014 Alaska trip...)
Please, keep posting. Please keep researching. Please be a bit more selective in your wording... IMO, you got your wording wrong on this one
! (You know, maybe ask a questions of 'Why?' we might do more frequent oil changes then you do... Vs stating what you did.)
Best to you, and all,
